Question

unit exam-gravitational/electrostatic forces
a magnetic attractive force
allows magnets to decorate
refrigerators.

what sign is the interaction
between the refrigerator and
magnets?

positive negative

Explanation:

In the context of force interactions (like in physics, where attractive forces are often represented with a negative sign in some conventions, as attractive interactions are considered a negative interaction in terms of potential energy or force sign conventions when using coordinate systems or force - interaction sign rules). Since the magnet and refrigerator have an attractive magnetic force, the interaction sign is negative.

Answer:

Negative
